Dear Employer, As you can see in my profile I have vast experience in the payment sector (+17 years) with similar solutions done to the one described. Will be very useful if you can provide me a requirements document to better quote. Some questions that come to my mind are: - the vendor's login is to the POS? - the NFC interaction between card/terminal is following EMV? - what security constraints has to be considered? - the development is just for the terminal or it includes the mDevice? Looking forward to your responses. Thanks, Paul
